Might not be the oil pressure valve.
dropping to 10 to 15 psi (hot) at idle is fairly common on moderate milage
engines.
If the pressure is lower than that, and come up quicky with revs, suspect a
partially
opened relief valve.
If this is the case, dont modify it, replace it.
There is a oil pressure relief valve tech note at:
